Specification of Letters Patent. Patented Hwy, 25, 1919,,

Application filed January 18, 1919. 'Srial No. 271,8?2.

To all whom it may concern Be it knownthat I,"'VVILLIAM BLACKER, asubject of the King of Great Britain and Ireland, residing at 62 StocksLane, Stalybridge, in the county of Lancaster, England, engineer, haveinvented new and usefullmproveinents in Puppet-Blocks, Puppets, and likeDevices Used in Connection with the Pressing, Stamping,- and I Treatmentof Metals, of which the following-is a specification.

This invention relates to puppet blocks, puppets, and like fittings,such as jingler blocks, which can be used with mechanical hammers orother stamping or pressing, stripping, or like mechanisn'i usedin-connection with the die stamping or pressing of metal, pressed diework, and such like;

It known to use detachable puppets ap plied to a puppet block, thepuppets having long shanks socketed'in holes in the block ach puppetbeing held by a cotter passedthrough a slot or opening in the puppetblock and fitting a slot in the shank of the puppet. Such detachablepuppets are not only expensive to make as they require to be turned andfitted, but in some situations they are troublesome to apply andrenew'because of diiiiculty in getting at the cotters.

According to my invention, I fashion the puppet or other block, such asa, jin'gler block, with a number of undercut grooves, 0r beveled edgechannels or dove-tail guideways upon its upper face and radiating fromthe center at which the dieblock or the like is applied. For example Imay provide four undercut'grooves, one at each corner of a square puppetblock, although this may vary. Such undercut grooves are slightlytapered, diminishing a little in width as the center of the puppet blockis receded from.

I employ readily attachable and detachable puppet devices which are ofmetal and have their lower part or foot slightly tapered and also alittle inclined whereby each one can serve as a sliding block capable ofengaging and locking with its particular undercut roove in the puppetblock casting. In the case of four puppets to be fitted they areseparately applied by outward direction from the center of the puppetblock by being knocked into position each to firmly engage its set ofundercut grooves. Said undercut grooves firmly hold and sup port thepuppets and vet allow of the ready removal or renewal of a brokenone; orif need be the use of puppets of different size or design.

I bore each puppet and tap the same for application a screwed stud'orspindle which several screwed studs or spindles hold the die blockaswill be understood.

I also saw orcut each puppetlongitudi nally and. down to the screwthread and apply transverse bolts withnuts or equivalent means, with theobject of allowing me to clamp the adjustable holdingscrews for the dieblock or the like.

The invention is illustrated in the accompanying drawings in whichFigure l is an elevation ofa jingle'r'block constructed in accordancewith my invention one of the puppets being removedfthe view beinganelevation of Fig. 2 looking. in the direction of'thearrow.

- Fig. 2 is a plan view of Fig. l.

T he jingler block a is of ordinary or usual construction, such as isused with Oliver hammers.

undercutlgrooves to facilitate the insertion of the puppet block andremoval thereof.

The puppet devices 9 under my invention,

which are readily attachable and detachable, are of metal and are formedw1th a foot it slightly tapered and inclined so as to engage with andlock in its particular undercut groove 0. The four puppets shown areseparately inserted in position from the center and knocked or wedgedinto position each in its undercut groove, where they are firmly heldand yet can be readily removed, in case it is necessary to renew abroken puppet or for using puppets of different size or design. Eachpuppet g is bored and tapped for a screwed stud 15 formed with squareends j to enable same to be rotated by a suitable key or other device,and with rounded heads and these screwed studs in the drawings.

are adapted to hold the die block (Z as shown The puppets g are also cutlongitudinally to form a slot m down to the screwed thread toenablethepuppets to be clamped firmly on the screwed studsc' by means oftransverse bolts 11,.

By my invention I can producecheap-and strong puppets and apuppet blockcapable of having my puppets readily applied thereto, removedor renewed,the puppets servlng to firmly support, bind and hold the adjustingscrewsfwhich bear on and confine the die block or its like. v i y Thebore and thread tapped in each puppet may be at. any desired angle andthe actual design of the puppets may vary.

It might be possible in large SlZQClPUP- pets to havesprojections fromthe puppet block engaging with rotatable .in said, bore and adapted toen-- gage said die,'ia'nd cooperating means carried: by said block andsaid members for limiting the backward bers.
